' METALLIC SHING'LEL SPECIFICATION forming part of Letters Patent No.381,318,61ated April 17, 1888.

To all whom it may concern.-

Be it known that I, EDGAR ELIN BARKER, of Junction City, in the countyof Davis and State of Kansas, have invented a new and usefulImprovementin Metallic Shingles, ofwhich the following is aspecification.

1 My invention relates to metallic shingles or roofing-plates designedto be fitted and nailed to the sheathing, so as to'interlock and form awater-tightroof,without'soldering or crimping of seams; and it consistsin the peculiar construction of the plate, which I will now proceed todescribe with reference to the drawings, in whi'ch Figure 1 is aperspective view of one of the metallic shingles; and Fig. 2, a planview of a group of the same, showing the manner of laying the same.

A represents the plate or shingle. These are all made alike and in onepiece, and are formed with a hook-shapedlocking edge, a, on one side anda hook-shaped locking-edge, b, on the other side. The locking-edge a isformed by bending the metal at the edge of the plate up and then downand around untilit forms nearly a perfect tube, which extends from thetop to the bottom end of the plate. The other hook-shaped edge, 6,lSfOIlDed by bending it up, then over and around in the same directionas the edge a until it nearly touches the body of the plate, and thenreturning the metal (so as to make this hooked edge doublethick ness)and extending the terminal edge at c in the plane of the body of theplate, which edge 0 forms the nailingflange by which the plate isattached to the roof.

The hook-shaped edge b differs from a in several particulars. First,itis of double thickness, which is rendered necessary in order to getthe nailing flange c; secondly, it is of smaller curvature than a, sothat the hoo'ked edge a of the adjacent plate will readily slide over ortelescope upon it; and, thirdly, this hooked edge 1) extends only aboutthree-quarters of the length of the shingle, ivhich latter is cut awayat its lower right-hand corner,leaving a tapering lip or curled edge,(1, extending from the lower end of hooked edge I) to the lower edge ofthe shingle. The function of this lip d is to enter the top end of thehooked edge I; of the shingle below, and thus bring the a, is slippedupon the edge I) of the last nailed hooked edges b b of the verticalseries of shingles into coincidence or alignment.

To apply the shingle, the larger hooked edge,

plate, and then slid downwardly until it reaches the lower tier ofplates, as at m. The curled edge or lip 12 is then entered into thehooked edge I) of the lower plate, and the plate is then slipped down toits destination, whereit overlaps the lower plate. At the'lefthand edgeof theplate, where the large hooked edge a of one plate coincides withthe large hooked edge a of the next lower plate, it is necessary tostrain the upper edge over the lower edge, which the flexibility of themetal permits to be easily accomplished, and which, when done,

serves to make a lighter joint and a stronger roof. The large edge a ofone plate only telescopes over the large edge of the next lower platefor a short distance, whichis equal to I the length of the curled lip d.

At the top and bottom of the plates are transverse ridges, which serveto prevent rain and snow from beating up under the lap of the plates,and the lower edge of each plate is canted slightly downward for thesame purpose.

Any ornamentalfiguremay bestamped upon the plate, if desired.

Having thus described my invention, what I claim as new'is- 1. Theroofing-plate or metallic shingle having a ho0k-shaped edge, at,extending its entire length on one side and a hook-shaped edge, I), ofsmaller diameter, on its other side, extending only a part of its lengthand formed of double thickness,with a nailing-flange, 0, sub stantiallyas and for the purpose described;

2. The roofing-plate or metallic shingle having ahook-shaped edge, a,extending its entire length on one side and a hook-shaped edge, b, onthe other side, of smaller diameter, extending a part of its length andofdouble thickness,with nailing-flange c, and'the curled lip or flanged, extending from the bottom of hooked edge b to the lower end of theshingle, substantially as and for the purpose described.
